摘要： A host system is provided with a shared resource (such as work queues and completion queues); multiple processors arranged to access the shared resource; and an operating system arranged to allow multiple processors to perform work on the shared resource concurrently while supporting updates of the shared resource. Such an operating system may comprise a synchronization algorithm for synchronizing multiple threads of operation with a single thread so as to achieve mutual exclusion between multiple threads performing work on the shared resource and a single thread updating or changing the state of the shared resource without requiring serialization of all threads.

摘要： A host system is provided one or more hardware adapters; multiple work queues each configured to send and receive message data via said one or more hardware adapters; multiple completion queues each configured to coalesce completions from multiple work queues belonging to a single hardware adapters; and a completion queue management mechanism configured to check for completions across multiple completion queues in the context of either a single thread or multiple threads of operation.

摘要： Methods and system for a message resource pool with asynchronous and synchronous modes of operation. One or more buffers, descriptors, and message elements are allocated for a user. Each element is associated with one descriptor and at least one buffer. The allocation is performed by the message resource pool. The buffers and the descriptors are registered with a unit management function by the message resource pool. Control of an element and associated descriptor and at least one buffer is passed from the message resource pool to the user upon request by the user. The control of the element and associated descriptor and at least one buffer is returned from the user to the message resource pool once use of the element and associated descriptor and at least one buffer by the user has completed.

摘要： In an example embodiment, a method of transferring data to or from an input/output unit across a network emulates a message passing protocol. A message sent from a host device to the input/output unit specifies the requested data transfer and is formatted in accordance with the message passing protocol. An emulation service software layer on the input/output unit translates the message into a corresponding series of data transfer operation instructions. The series of data transfer operation instructions have a different format than the format of the message passing protocol. The data transfer specified by the message is carried out by the operating system and hardware of a target device in the input/output unit using the series of data transfer operation instructions. After the data transfer is completed, a reply message is created in the emulation service software layer and the reply message is sent to the host device in a format according to the message passing protocol.
